Mining has been there since the civilization started. As the time passed by people started incorporating some rudimentary techniques and tools for extraction of materials. These days mining industry uses Heavy Earth Moving Machineries (HEMM) for the extraction. These machinery have high initial cost or setup cost and high maintenance cost as well. So it is essential to utilize this machinery optimally if not, it would neither fulfill its purpose nor justify its cost. To use this machinery optimally, it is inevitable to know information pertinent to the availability and utilization of it. The availability and the utilization are parameters to reckon the efficacy of the machinery. Data were collected from two open cast metal mines i.e. lanjiberna limestone mine and Kurmitar iron ore mine respectively. Data contains scheduled hours, idle hours and maintenance hours. Using the data rom these mines, Availability, utilization and overall equipment effectiveness was calculated for the past one year. And obtained results were shown by using graphs and bar chart. After scrutinizing the results, the probable cause for the decrement or diminution of availability and utilization were established. The machinery which was used in this case are Excavators, Dumpers, Tippers and Loaders. This study will be helpful for improvement in utilization of machinery and by this,the productivity will also increase. In the current case, it has found out that there has been the irregular behavior of the utilization and availability percentage.
